Introduction : Relative Energy Deficiency in Sport (RED-S), is a syndrome which can adversely affect the health and performance of athletes. It exists when there is a negative balance between dietary energy intake and the energy expenditure required to support optimal health, daily living activities, growth, and sport. Although much of the research and literature relating to RED-S has been an outgrowth from studies of the 'Female Athlete Triad', it is important to note that the condition can affect men and women, able-bodied and disabled populations, and individuals of various races. Athletes, parents, coaches, and medical practitioners need to understand the signs, symptoms, and dangers of RED-S in order to identify athletes who are in danger of developing, or already have, the syndrome and to determine an appropriate treatment.

Key Messages : 1. RED-S may affect men or women. It is most prevalent in sports/activities where leanness/weight are important for performance; aesthetics/appearance; or to meet a weight category. 2. RED-S is caused by low energy availability and can have long-term health impacts for both women and men. 3. Diagnosis and treatment of RED-S should be completed by a team of medical specialists.
